On a clear summer night, look up to the sky and what do you see? Ordinary matter such as planets, stars maybe even an asteroid. Millions of little specks, as far as the eyes can reach. This ordinary matter, also known as baryonic matter, is the primary observable component of our universe. But is what we see all that is out there?
The deep seafloor covers around 70% of our planet’s surface and is home to a diverse community of microorganisms, mostly bacteria. These single-cell life forms inhabit some of the most extreme places in the world, with freezing waters, permanent darkness, high pressure and little food. ERC grantee Antje Boetius studies these microbes in the abyss and their important role for the Earth’s nutrient cycles.
Until recently, lungs were believed to be sterile, but today we know that they are inhabited by microbes migrating from the mouth. Dr Randi Bertelsen has been awarded an ERC grant to investigate the role played by the oral microbiome in lung disease.
Severe traffic jams not only have an impact on mobility, they also raise environmental and health issues linked to fuel consumption and air and noise pollution. Prof. Ludovic Leclercq is developing new traffic control models that could tackle road congestion while integrating a green dimension.
If you raise your eyes to the sky, you won't see it but you might sense it passing by. On 12 January just before sunrise in Europe, PicSat, a cube satellite as big as a shoebox and barely as heavy as a brick, will be launched from the Satish Dhawan Space Centre in Sriharikota, India. Supported with a grant from the European Research Council, it is the first nanosatellite to embark on one of the greatest space adventures: exploring, from afar, an exoplanet.
Could migration lead to more respect for ethnic and cultural diversity not only in receiving communities but also in sending countries? By observing the effects of Polish migration to the UK and Germany, as a result of the country’s entry in the EU in 2004, Prof. Magdalena Nowicka explores possible answers to this question.
Different responses might be given to global challenges. For example, how should the vanishing of a glacier be tackled? Prof. Thomas Eriksen aims to understand the economic, environmental and cultural transitions the world is going through and the responses created by local communities in order to offer valuable advice to our policymakers and leaders.
While women inherit two X chromosomes, the expressions of one of them is shut down during embryonic development. Men have one X chromosome and one Y chromosome. The switching off of women’s second X chromosome is thought to compensate for the presence of only one X in males versus two in females, to balance for X-linked gene products between the sexes. X-chromosome inactivation is also one of the clearest examples of what epigenetic mechanisms do to our genetic material: the DNA of the genes on the X is still present but not actively expressed or needed. Prof. Edith Heard was awarded ERC grants to understand the intricate processes behind the phenomenon, with unexpected results that changed the way gene regulation is now looked at.
Prof. Ian Thomas Baldwin received an ERC Advanced Grant to study the internal circadian clock of plants. In particular, he wants to understand the ecological consequences of plants fallings ‘out of synch’. In this interview, Prof. Baldwin shares some of his research findings and explains why he has chosen to make his study results openly available.
An international research team led by astronomers from the Max Planck Institute for Radio Astronomy (MPIfR, Bonn, Germany) used a collection of large radio and optical telescopes to investigate a newly discovered pulsar, and its white dwarf companion. The observations revealed a system with unusual properties, which weighs twice as much as the Sun, making it the most massive neutron star to date. These findings partly result from the “BEACON” project led by ERC Starting grantee Dr Paulo Freire, and agree with Einstein’s theory on general relativity. They will be published in tomorrow’s issue of Science, April 26, 2013.
